This simple Hot Cross Bun Mug Cake has all the flavours of a traditional Hot Cross Bun. It’s so easy and you can make it in minutes in your microwave.
Why should I make a Hot Cross Bun Mug Cake?
Sometimes I crave a special sweet treat. This recipe for a Hot Cross Bun Mug Cake really hits the spot. There’s no need to nip out to the shops to buy something because I can mix up a few ingredients and make this spicy cake my microwave in minutes.
This little cake has a great texture and, although it took me a few trials I’ve finally cracked it and got the right balance of fruit, spice, and sugar, so it really tastes just like a Hot Cross Bun.
What are Hot Cross Buns?
Hot Cross Buns are a type of sweet bread bun, spiced with spices such as cinnamon and nutmeg and speckled with dried fruit and candied peel.
The origin of the Hot Cross Bun may go back to the 12th Century when it is said that they were baked by monks and marked with a cross to honour Good Friday. However, there is an alternative theory that the baking of cross buns may go back even further to Pagan times. When these buns were baked at the beginning of Spring to celebrate the goddess Eostre.
Whatever their origins Hot Cross Buns are so good that we are still eating them centuries later. The tradition is to eat these sweet yeasted buns on Good Friday. In the UK we love Hot Cross Buns so much that they are available to buy all year round.

What ingredients do I need to make a Hot Cross Bun Cake?
The ingredients I use for this mug cake are standard baking ingredients that are easily available and you probably have most of them already. Here is what you need:
- butter
- egg
- milk
- brown sugar
- mixed spice
- mixed dried fruit
- self-raising flour
- cocoa powder (optional)
A full list of the ingredients and the required quantities is found in the recipe card at the end of this article.
Can I use a plant based spread instead of butter?
Yes, any full fat spread will work with this recipe. Avoid low fat spreads as they are not suitable for baking.

Should I use light brown or dark brown sugar?
I use light brown sugar in the Hot Cross Bun Mug Cake recipe. It brings a slightly caramelised flavour to the cake. You can use dark brown sugar but the stronger flavour may overpower the taste of the spices.
Can I use white sugar?
If you don’t have any brown sugar then you can use white sugar, either granulated white sugar or caster (superfine) sugar.
What is mixed spice?
Mixed Spice is a spice blend readily available in UK supermarkets and baking suppliers. It is a combination of the following ground spices:
- allspice
- cinnamon
- nutmeg
- mace
- cloves
- coriander
- ginger
If you can’t source ready-made mixed spice you can make your own. Or you can use cinnamon with a pinch of nutmeg or cloves.
What is mixed dried fruit?
Mixed dried fruit combines dried vine fruits such as raisins, sultanas (golden raisins) and currants (zante currants) with chopped candied citrus peel. You can buy bags of this mix in most supermarkets in the UK.
I can’t find mixed dried fruit, what can I substitute?
You can use about 80% raisins and/or sultanas to 20% chopped candied peel. If you can’t source candied peel then you can add the grated zest of half an orange to the mix to give the citrus flavour to the Hot Cross Bun Mug Cake.

I don’t have self-raising flour, what can I substitute?
If you don’t have self-raising flour you can make it at home using plain (all-purpose flour) and baking powder.
This recipe uses 3 tbsp of self-raising flour therefore you need to add 1/4 tsp of baking powder to plain (all-purpose) flour.
What do I use the cocoa powder for?
I use cocoa powder to make a cross on top of the mug cake. It’s optional because it’s only there to make the cake look like a hot cross bun. If you don’t have any or you don’t want to use it, the mug cake will still taste very good.
How do I make the cross on the Hot Cross Bun Mug Cake?
If you’d like to create a cross on top of your mug cake, then check out the video I made. It will show you how I created a simple template using aluminium foil then dusted over cocoa powder.
Can I do any preparation ahead of time?
The only thing you could really do, is mix up the dry ingredients. As the cake takes only 3 minutes to cook in the microwave it’s not something that you really need to prepare ahead of time. And like all mug cakes, it’s best eaten soon after it has been cooked.
Can I double the recipe?
A Hot Cross Bun Mug Cake is a real indulgence when you are on your own, but if you want more you can easily double up the recipe and make two mug cakes. However, you will have to cook each one separately as otherwise the timings will be out.
How do get the cake out of the mug?
Just run a blunt knife around the edge of the mug to loosen the cake. It should then come out of the mug easiley.
Vegetarian
The Hot Cross Bun Mug Cake is suitable for vegetarians.
Gluten Free
This cake contains wheat flour and is not suitable for a gluten free diet.

How should I serve the Hot Cross Bun Mug Cake?
I like to serve it still warm, split in half with lots of butter. This is how I’d eat a yeasted Hot Cross Bun and it is my favourite way to eat this mug cake too.
It also makes a delicious quick and easy dessert. Simply serve the cake in a bowl with cream, ice cream or with either bought or homemade custard.

Chris @thinlyspread says
Oh my! I am a new microwave user, I think this will be my first mug cake, how fab!
Janice Pattie says
Oh I’m so pleased Chris. I use my microwave a lot but mainly for reheating and defrosting, it’s a whole different thing baking in it, but a bit of perseverance and I was pleased with how it came out.
Corina says
I love the fact you can still butter it like a ‘real’ hot cross bun! It looks like the texture is good too.

kellie@foodtoglow says
SO CUTE!! Great idea. Can I ask you Janice how you achieve your half an egg, or do you make two? Pinning, etc :_
Janice Pattie says
Thanks Kellie, you could make two, I just guessed half the egg after beating it, but I suppose you could weigh it if you wanted to be accurate, I made I
The mug cake three times and it didn’t seem to matter if the egg amount was accurate.
Katy says
Absolutely love this idea. So clever and sounds delicious x
Janice Pattie says
Thanks Katy, it was fun to make
Sammie says
This is such a brilliant idea. Shame on me that I’ve not yet made a mug cake. Love this and love hot cross buns so perfect combination. Great post. Sammie X.
Janice Pattie says
Thanks Sammie, hope this has inspired you to have a go at making a mug cake.
Dom says
oh my word! What a genius idea. I love how it still looks quite bready too. I’ve yet to make a mug cake… well, I made one once but it wasn’t very nice so I need to try again. Thanks so much for linking to Simply Eggcellent xx
Janice Pattie says
Thanks Dom, my previous mug cake experience wasn’t good either, so I worked hard on this one to get the texture and flavour right.
[email protected] says
Wow… I love this. It is so cool and cute, and it is quick and easy, looks delicious. I can’t wait to try this and share with my family. I am also thinking to use cheese to make the cross on top. 🙂
Janice Pattie says
Thanks yung, I guess cheese would work, although it is quite a sweet cake.
[email protected] says
I tried it twice. It is delicious, but quite difficult to maintain the shape when takes it out from the mug. Also, when adding in the flour, it forms lots of lumps, take me some efforts to make the batter smooth. I have reduced the sugar added when trying for the second time, it is too sweet for me. 🙂
Janice Pattie says
Thanks for letting me know how you got on. Perhaps a little oil or butter around the mug might help get it out in one piece. The sweetness is a matter of taste I guess.
Glamorous Glutton says
What a great idea, very clever. I’ve bought a couple of mug cake books but not actually made any. I love hot cross buns so this would be a great last minute treat. GG
Janice Pattie says
Thanks Amanda, you should get those books out and try some recipes!
Emma @ Adventures of a London Kiwi says
Get in mah belly *insert proper comment here after mouth stops watering*.
Such a clever idea to use the tea bag strainer!
Janice Pattie says
Thanks Emma, it’s just a tiny sieve really, I use it quite a lot!
Choclette says
I’m super impressed, your cake really looks like a hot cross bun when you slice into it. Also impressed with your video. As the cocoa features in that so strongly, I’m so glad you shared it with We Should Cocoa.
Janice Pattie says
Thanks Choclette. I was so pleased with the result and it simply wouldn’t have looked so good without the dusting of cocoa to make the cross. Hoping practice makes perfect with the videos!
